Application sied November io, 1914. serial no. 871,294. To all whom it may concern Be it known that we, ALois STAUBACH and GEORGE VUNAK, citizens of Austriaungary, residing, respectively, atChicago and Blair Station, in the counties of Cook and Alleghenyl and States of Illinois and Pennsylvania, have invented a new and useful Detachable Sole and Heel for Shoes; and we do hereby declare the following to be a full,.clear, and exact description of make and use the same. l

This invention relates to the art of shoes,

and particularly to an improved detach- .able'sole and heel. f

i" As'an object of the invention it is the aim to provide means for enabling a soleand heel to be attached and detached, wherebyv heel may be removed, 'and a leather sole and a rubber sole and heel substituted and vice versal, andas required or desired by the wearer. One of the features of the invention is the provision of a skeleton frame embedded in the inner fsole, and a correspondingly shaped skeleton frame embedded in t'the sole and heel', there being inter-engaging lugs and recessesor depressions for. the two frames, and a key controlled lock frames together in suoli Wise as to prevent the lugs and recessesxor vdepressions from accidental disengagement.

In practical fields the details ofconstruction -may necessitate alterations, falling within the scope of what /is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown inl the drawings and claimed.

In the drawings r-Figure' l isa longitudinalsectional view through a shoe, showing the same equipped with the improved mechanism for attaching and detaching the Fig. 2 isa transverse sectional view on line 2`2 of Fig. -1.- Fig. 3 is an enlarged detail sectional view showing partsv in elevation of the twoskeleton frames andthe locking mechanism between thek frames in coperation.

and showing the shoe Fig. l is a view similar to a ke)7 inserted. whereby lockingv mechanism between the .two rames may be unlocked. Fig. 5 is a plan in. dotted lines. Fig. 3. showing the .ing the lugs 9,

view of the skeleton frame. which is carried between the inner part of the inner sole and the bottom pa i't of the inner sole. Fig. (i is a plan view of the skeleton frame and which is embeddedin the detachable `sole. Fig. 7 is a sectional view on line 7--7 of Fig. 3.

eferring more particularly to the drawings, 1 designates the upper of a shoe ha"- ing an insole, consisting ot' two parts 2 and 3, which areso constructed and arranged together as shown in the drawing as to rein the manner illustrated, which frame 4 is a pluralityof recesses or depressions 5. ranged on the part 2 ofthe insole is a sock lining 2, These recesses 5 are provided with enlarged portions and narrow \`por tions. The sole 7 of the shoe consists of the embedded engage i beyond they narrow I portionfsf otv the recesses, thereby preventing the two iframes from separating; The; traine ils pi-o'\ led with a transverse bar 12 a rein forced .fr yftlie short longitudinal bar 13 extcnding'to extreme heel of the traine.vv iftendino'` slightly forwardly from theunder portion .of the extreme heel of thefrauie4` is? an ex,-

in a pair of rollsi :20 extends and through lstorined. The' latch 17 is provided with a downwardlyextendL ingflange 26. The traine 8` adjacent the heelthereof is provided witira transverse Y 7 recess 2S and an'opening which` is also ornied in the longitudinal bar r3.0, `which integrally connects the expart 7a being ar? ls'a frame and contour to the provided with Y parts of said recesses and,theeextensioiis 11 f provided` downwardly,

' The end of v treme heel portion and said bar Mounted upon and secured to the under portion of the bar 2T is an arched plate 31. and extending rearwardlv from the arch is an eX- tension 2"2, bent downwardly toward and secured to the cxtreme heel of the frame S in an suitable manner` such asby soldering. The arched plate may be secured to the bar 2i' in an \Y suitable manner. for instance b v soldering. The extension is provided with two downwardl)Y extending ears 3?. in which a pin 34 is mounted. livoted on the pin 34 is a latch releasing member 35, the forward portion of which is provided with a slot 3G through which the neck 3T between the plate 3S andthe arch 31 is received.

rl`he forward portion ot' the. latch releasing rneniber engages over the plate 39,' and is provided at its extremity with an up-` wardtt' extending lange 39.

The latch releasing member 35 is provided with a key pocket, to receive. the key 40,; which is inserted in the pocket between the. plate 3S and the latch releasing member` thereby forcing the latch releasing' member upwardly,k causing theheaded pin 41 (which is guided in 'the opening ot' the Irear extension 31).) to contact with the lug-dot the latch'. so' y thereby pathvz'of the )ressing the latch 1T in this manner. a longitudinal :forwa rd movement maybe imparted tothe t'ram'e 8. so as to Vpermit the plurale ity of headed lugs ot' the frame S to disengage said recesses of the fr: 'n The lugs and recesses are not only disengagedl in this manner1 but also the lhg 4.4' ot the framev 4 is disengaged from the recess lg'iot' `theftoe portionjof the frame.' The headedpin 41 is laetuated againstl the' actioiiiiofthe leaf Spring 47. c c, The pin 41 Avis provided `\'\-'ith' oppositely disposed recesses or the forks49 of the p'ii"-41f'n the latch releasing lnembelu 4The i key Ulis slotted 'as y sionoti'thel-pin 41, when thekey is'ji'nserted recesses for vlocking said `f releasing member.
